What is the best righteous deed by which a Muslim man or woman draws near to Allah?

Question:
What is the best righteous deed by which a Muslim man or woman draws near to Allah, may Allah preserve you?

Answer:
Answer: Yes, the obligatory acts. The Prophet (peace and blessings be upon him) said, reporting from his Lord (Mighty and Majestic), that Allah (Exalted and Majestic is He) says: “My servant does not draw near to Me with anything more beloved to Me than what I have made obligatory upon him. And my servant continues to draw near to Me with voluntary acts until I love him. When I love him, I become the hearing with which he hears, the sight with which he sees, the hand with which he strikes, and the foot with which he walks. And if he asks Me, I will surely give to him, and if he seeks My protection, I will surely protect him.” This is a great hadith that indicates that Allah is with His believing servant in a special way, granting him success in his limbs and organs so that he does not use them except in the obedience of Allah (Glorified and Exalted is He).
